Automatic responses to brief expression changes from a neutral face have been recently isolated in the human brain using fast periodic visual stimulation (FPVS) coupled with scalp electroencephalography (EEG). Based on these observations, here we isolate specific neural signatures for the rapid categorization of each of 5 basic expressions, i.e. Read More

Purpose Of Review: The current review focuses on studies investigating the factors related to the development of preferences for foods and sensory inputs (tastes, odours, and food textures) in the first years of life, which constitutes a specific window for food learning.

Recent Findings: Foetal nutrition, intrauterine growth, and prematurity influence food preferences; this topic warrants more research to broaden our understanding of the 1000 days phenomenon. Although it is less studied than other sensory inputs, food texture acceptance, and the related sensitive period for texture introduction are attracting more attention, as is the impact of fat acceptance.

Introduction: The aim of this work is to evaluate the impact of the timing of pre-infusion serum uric acid (sUA) test results for use in applying stopping rules for pegloticase to identify patients at risk for infusion reactions (IRs) while on therapy.

Methods: Data from the phase 3 clinical trials of pegloticase were reviewed and individual uric acid levels of the 85 patients who received the approved regimen of biweekly infusions were examined in relation to the occurrence of IRs.

Results: Of the 22 patients (26%) who experienced an IR on pegloticase therapy without uric acid stopping rules, only seven (8%) would have had IRs if pegloticase therapy had been discontinued after two consecutive pre-infusion sUA levels above 6 mg/dl. Read More

Objective: Inflammation-related symptoms such as pain, swelling and tenderness of the affected joint are frequently assessed using 5-point diary rating scales in gout clinical trials. Combining these into a single gout attack symptom intensity score may be a useful summary measure for these data, which is potentially more responsive to change compared with the individual components. The objective of this study was to develop a patient-reported gout flare intensity score, the Gout Attack Intensity Score (GAIS), for use in clinical studies, that includes components for gout-related pain, swelling and tenderness.

Infants' olfactory experience begins before birth and extends after birth through milk and complementary foods. Until now, studies on the effects of chemosensory experience in utero and/or through human milk focused on experimentally controlled exposure to only 1 target food bearing a specific odor quality and administered in sizeable amounts. This study aimed to assess whether early olfactory experience effect was measurable in "everyday conditions" of maternal food intake during pregnancy and lactation, and of infant intake at weaning, leading to expose the infant to corresponding odors as fetus, neonate, and infant up to 8 and 12 months of age.

The enhanced differentiation and activation of osteoclasts (OCs) in the inflammatory arthritis such as rheumatoid arthritis (RA) and gout causes not only local bone erosion, but also systemic osteoporosis, leading to functional disabilities and morbidity. The induction and amplification of NFATc1, a master regulator of OC differentiation, is mainly regulated by receptor activator of NF-κB (RANK) ligand-RANK and calcium signaling which are amplified in the inflammatory milieu, as well as by inflammatory cytokines such as TNFα, IL-1β and IL-6. Moreover, the predominance of CD4 T cell subsets, which varies depending on the condition of inflammatory diseases, can determine the fate of OC differentiation. Read More

The increasing prevalence of hyperuricemia has been recognized as an emerging public health concern in both developed and developing countries. Hyperuricemia is a metabolic condition characterized by an elevated serum uric acid, and associated with renal damage, diabetes, autoimmune disorders, and cardiovascular diseases. Although human genetic variation has been recognized as a factor, posttranslational cellular processes and glycan biomarkers have not been studied extensively for susceptibility to hyperuricemia.

Objective: Acute gout is a painful, inflammatory arthritis that features a rapidly escalating inflammatory response resulting from the formation of monosodium urate crystals in the affected joint space. Previously, we found that Chuanhu anti-gout mixture (CAGM) had similar effects as colchicine against gout in the clinic. Subsequently, to improve its effectiveness and efficacy, we modified the original formulation of CAGM. Read More

The nucleotide salvage pathway is used to recycle degraded nucleotides (purines and pyrimidines); one of the enzymes that helps to recycle purines is hypoxanthine guanine phosphoribosyl transferase 1 (HGPRT1). Therefore, defects in this enzyme lead to the accumulation of DNA and nucleotide lesions and hence replication errors and genetic disorders. Missense mutations in hypoxanthine phosphoribosyl transferase 1 (HPRT1) are associated with deficiencies such as Lesch-Nyhan disease and chronic gout, which have manifestations such as arthritis, neurodegeneration, and cognitive disorders.

In olfaction, to preserve the sensitivity of the response, the bioavailability of odor molecules is under the control of odorant-metabolizing enzymes (OMEs) expressed in the olfactory neuroepithelium. Although this enzymatic regulation has been shown to be involved in olfactory receptor activation and perceptual responses, it remains widely underestimated in vertebrates. In particular, the possible activity of OMEs in the nasal mucus, i. Read More

Objective: Gout is the most common inflammatory arthritis worldwide, and patients experience a heavy burden of cardiovascular and metabolic diseases. The inflammation is caused by the deposition of monosodium urate (MSU) crystals in tissues, especially in the joints, triggering immune cells to mount an inflammatory reaction. Recently, it was shown that MSU crystals can induce mechanistic target of rapamycin (mTOR) signalling in monocytes encountering these crystals in vitro. Read More
